Answer:
Explanation:
The height is the perpendicular bisector of the side opposite the vertex and divides the triangle into two equal triangles with right angles.
The angle opposite x is divided into 30 ° - it was 60.
We can use the tan ratio of that angle to find x.
tan = opposite/adjacent
. 57735027 = x/9
.57735027(9) = x/9 · 9/1
5.196 = x
round to nearest tenth = 5.2
